NFL's Donald Penn Still Gunning To Play This Season, Call Me, Rams!

Three-time Pro Bowler, Donald Penn, says he ain't callin' his NFL career quits just yet ... the offensive lineman tells TMZ Sports he's ready to play if a playoff team needs him!!

And, with the Rams recently losing left tackle Andrew Whitworth to a knee injury ... the dude says Sean McVay should hit him up!!!

"Why ain't y'all call me yet, man?!" Penn says. "McVay, come on, baby. You my dog! You know what I mean? Hit me up if you need me!"

Penn last played for the Washington Football Team in 2019 -- starting 15 games and performing well.

But, the 37-year-old didn't get the opportunity to latch on with an NFL team this year ... causing some to believe retirement might be on the horizon.

Penn, though, tells us he's still in game shape and ready to help a team make a run at a Super Bowl.

"I mean, it's crazy," Penn tells us. "Sometimes I watch and I'm like man, I look at some of these young cats out here and I'm like, 'Wow, like what are they doing?' I'm like, 'I can do that easily still in my sleep now.'"

Penn says if the opportunity is right -- like playing for a Super Bowl contender like the L.A. Rams -- he'd be down to sign a contract in a heartbeat.

"I'm still staying in shape, ready to go if somebody needs me," Penn says.

There's more ... we also spoke with Penn about his ex-teammates, Derek Carr and Dwayne Haskins -- and he tells us he's sure the two QBs are going to rebound from up-and-down seasons this year.
