Calvin Johnson to protect finger

ALLEN PARK, Mich. -- Detroit Lions wide receiver Calvin Johnson confirmed to ESPN.com on Wednesday that he has received a fabricated splint to put on his once-injured finger for protective purposes only.

Johnson had surgery on his injured finger after the 2013 season and declined to provide more details about the splint or the finger following practice Wednesday. It is unclear how often Johnson plans to wear the fabricated splint. In the spring, Johnson said the finger was stuck at 90 degrees during the 2013 season. In the 2012 season, he also played with injured fingers.

He has shown no ill effects of either his finger or knee surgeries during training camp, as he has consistently beaten cornerbacks in drills.

Even with the finger and knee injuries last season, Johnson caught 84 passes for 1,492 yards and 12 touchdowns in 14 games. It was his third straight season with more than 1,400 yards.
