Forsett sent out a tweet with an appropriate GIF to mark the occasion:
Clifton Brown of CSN Mid-Atlantic confirmed with Forsett via text message that he agreed to a deal with the Lions.
Forsett's agent, Doug Hendrickson, sent out a tweet after the running back agreed with Detroit:
A late cut in training camp, Forsett re-signed with the Ravens before Week 1 and was their starter early in the season before falling out of favor. He posted 98 yards on 31 carries before being benched and eventually released at his request.
Ravens head coach John Harbaugh addressed the decision, via Ryan Mink of BaltimoreRavens.com:
Justin Forsett is a highly respected, highly valued guy in my eyes and the eyes of all of us. It is a competitive world that we are in. It is a competitive league; it is a competitive sport. He knows that as well as anybody. It doesn't diminish him in any way. It just enhances him, in my mind, in terms of how he handles it.
Forsett bounced around the league over the first six years of his career before seemingly finding a home in Baltimore. He shocked the NFL in 2014 by rushing for 1,266 yards and eight touchdowns, earning a Pro Bowl berth and seemingly establishing himself as the face of the Ravens backfield. But a down 2015 followed, and the team seemed ready to pull the plug in favor of its young backs this season.
It's unclear at this point how effective Forsett can be. In six of his past eight seasons, Forsett has averaged more than four yards per carry. He's at a very respectable 4.8 per attempt for his career.
"I'm at a phase in my career where I don't want to sit; I want to play. I have a lot of football left in me," Forsett said, per Mink.
Still, a combination of injuries and effectiveness concerns kept him on the fringes of NFL rosters before signing in Baltimore. It's more likely than not that 2014 was a one-year blip on the radar, and he's best served as an occasionally effective early-down back.
The Lions have used Theo Riddick, Dwayne Washington and Zach Zenner since Ameer Abdullah suffered a foot injury in Week 2. None of them have been particularly effective between the tackles, so it's possible Forsett sees extensive work.
