ALLEN PARK, Mich. — Detroit Lions wide receiver Calvin Johnson was back at practice Friday after missing the previous two days due to an ankle injury he suffered last Sunday against Green Bay.

Johnson was adamant all along that he was going to play Sunday against the New York Jets. But when Megatron misses practice, it is difficult to ignore.

“He’s one of those guys that physically, he’s an unusual individual,” Lions coach Jim Caldwell said Friday before practice. “He responds quickly to treatment. He bounces back pretty quickly for the most part. What would ordinarily take some guys a little bit longer, he seems to be able to fight his way through it.

“He has an extremely high pain tolerance, as well, and he prepares and takes care of his body every single day of the year. That’s where his focus is, and I think he benefits from that sort of regimen.”

Johnson has 19 catches for 329 yards and two touchdowns.

The news wasn’t all good for the Lions on Friday as tight end Joseph Fauria missed practice for a second straight day after injuring his ankle in a non-football activity Wednesday.
