Buddy taping, where you strap your jammed finger to the healthy finger next to it, is the most common way basketball players protect a sprain and keep playing. The technique takes about two minutes, requires only athletic tape and a small piece of padding, and still lets you grip, dribble, and shoot. Here’s exactly how to do it, plus an alternative method that gives you more ball feel at the cost of some stability.
Make Sure It’s Actually a Jam
A jammed finger is a sprain of the ligaments around a finger joint, usually caused by a ball striking the fingertip. The hallmark signs are swelling around the middle knuckle of the finger, tenderness when you press the sides of the joint, and pain when you try to bend or straighten it fully. You can still move the finger, even if it hurts.
A few signs suggest something worse than a simple jam. If the finger looks crooked or angled to one side, the bones may have shifted out of alignment (a dislocation). If you can’t bend the fingertip at all, a tendon may be torn. Severe pain that doesn’t settle down within the first 10 to 15 minutes, rapid bruising that spreads along the whole finger, or a joint that feels loose or wobbly when you gently wiggle it sideways all warrant an X-ray before you tape anything. Taping over a fracture or torn tendon can make the injury significantly worse.
What You Need
Medical cloth athletic tape (sometimes labeled “sports tape” or “zinc oxide tape”) is the best choice. It’s waterproof, holds up against sweat, and tears cleanly in any direction so you can size strips on the spot. Half-inch or 1-inch rolls both work. Use narrower strips near the fingertip and wider strips closer to the hand.
You’ll also need a small piece of cotton gauze, foam, or even a folded tissue to place between the two fingers. This padding prevents the skin-on-skin contact that causes blisters and moisture breakdown during a long game or practice. Make sure whatever you use lies flat with no folds or bunches.
How to Buddy Tape Step by Step
Buddy taping binds the injured finger to the healthy finger next to it. That neighbor finger acts as a natural splint, limiting side-to-side movement at the hurt joint while still letting both fingers bend and straighten together. For most basketball jams, this means taping the injured finger to whichever adjacent finger is closest in length.
Start by sliding your padding between the two fingers. It should sit snugly without shifting around. Then apply two strips of tape:
- First strip (closer to the hand): Wrap a piece of tape around both fingers between the big knuckle and the first finger joint. This is the anchor strip that controls most of the side-to-side motion.
- Second strip (closer to the fingertip): Wrap a second piece around both fingers between the first and second finger joints, closer to the tip.
The key rule is to leave the knuckle joints themselves uncovered. Taping directly over a joint locks it in place and kills your ability to flex the finger. By placing strips between the joints, you get stability where the ligaments are hurt while keeping the range of motion you need to catch a pass or curl your fingers around the ball.
Wrap the tape firmly enough that the two fingers move as a unit, but not so tight that you’re squeezing them together. After taping, check the fingertip of the injured finger. It should be its normal color and warm to the touch. Press the fingernail for a second, then release. The pink color should return within two seconds. If the fingertip turns white, blue, or feels tingly or numb, the tape is too tight. Peel it off and redo it with less tension.
An Alternative for Better Ball Feel
Standard buddy taping is great for protection, but linking two fingers together reduces your dexterity. Many basketball players notice a difference in shooting touch and dribbling control, especially on their dominant hand. If you’re dealing with a mild jam that’s already past the worst of the swelling, a check-rein tape job is worth considering.
Instead of wrapping two fingers together side by side, a check rein uses a short strip of tape that connects two fingers only on one surface (usually the top or bottom), creating a tether that limits the finger from bending too far in one direction. Each finger can still move somewhat independently, which preserves more grip and feel on the ball. The trade-off is obvious: you get less overall stability. This method works best for joints that are sore but not significantly unstable, and it’s a poor choice if the finger still feels wobbly or if it was recently dislocated.
For games where you need maximum performance on your shooting hand, some players buddy tape during warmups and practice, then switch to a check rein for the game itself. It’s a practical compromise between protection and control.
Keeping the Tape in Place During Play
Sweat and repeated ball contact loosen tape fast. A few habits help. First, dry both fingers thoroughly before you tape. If your hands run wet, a quick wipe with a towel and a light dusting of grip powder or chalk before taping helps the adhesive hold. Second, press the tape firmly onto itself after wrapping so the adhesive bonds fully. Third, carry a small roll of tape in your bag and plan to re-tape at halftime or between games. Tape that’s sliding around offers no support and can actually bunch up and irritate the skin.
If you find cloth tape loses its grip too quickly, pre-wrap (the thin foam underlayer used in ankle taping) around each finger before applying the cloth tape can add grip. Some players prefer self-adhesive cohesive bandage tape, which sticks to itself rather than to skin and holds well even when damp, though it’s slightly bulkier.
How Long You’ll Need to Tape
A mild jam with minor swelling and no joint instability typically feels significantly better within one to three weeks, though some stiffness and sensitivity to impact can linger for several weeks beyond that. Most basketball players tape the finger for the remainder of the season once they’ve jammed it, even after the pain fades, simply as a precaution against re-injury.
If the joint still shows moderate instability, meaning the finger shifts slightly when you push it sideways, the ligament damage is more significant and recovery stretches to four to six weeks or longer. During that window, buddy taping every time you play is essential, not optional. Joints with major instability, where the bones feel like they could easily shift out of place, often need medical treatment beyond taping, sometimes including a rigid splint or even surgery to repair the ligament.
A good rule of thumb: if your jammed finger hasn’t improved noticeably after two weeks of rest, icing, and taping, or if the swelling keeps coming back after each game, get it looked at. An X-ray can rule out a small fracture, and an MRI can show whether a ligament or tendon is torn rather than just stretched.
