Ravens at Lions

ESPN, 8:25 p.m.

Line: Lions by 6.

The lowdown: Calvin Johnson gives friends in the NFL and other players he admires the shirt off his back - literally.

The Detroit Lions superstar has exchanged jerseys with fellow receivers, Pittsburgh's Antonio Brown and Cincinnati's A.J. Green, this season.

"I've got eight to 10 hanging up, and eventually I'm going to get them signed and put up in my basement in frames on the wall," Johnson said. "I can't tell you when I first started doing it."

He doesn't expect the next time to be Monday night after Detroit (7-6) hosts the Baltimore Ravens (7-6) in a possibly pivotal matchup as both teams hope to close the month well enough to be in the playoffs.

"It's nothing personal, but I don't know any of those guys very well," Johnson said.

The two-time all-pro has 1,351 yards receiving - ranking second in the NFL, trailing Cleveland's Josh Gordon by 49 yards. He has caught 12 touchdown passes, behind only New Orleans tight end Jimmy Graham. - Associated Press
