The team announced the news via Twitter:
The then-St. Louis Rams selected Robinson out of Auburn.
This is just the latest move for Cleveland this offseason after becoming just the second team in NFL history to go 0-16. The Browns have acquired Tyrod Taylor, Jarvis Landry, Carlos Hyde, Damarious Randall, Baker Mayfield, Nick Chubb and more.
Despite all of those additions, however, the team also had to address the offensive line, as longtime left tackle Joe Thomas retired.
Cleveland signed veterans Donald Stephenson and Chris Hubbard back in March. Now, it has added one more body to the mix.
Robinson spent the first three seasons of his career with the Rams. After turning out to be a disappointment, he was traded to the Detroit Lions last offseason for a sixth-round pick. His time in the Motor City didn't last long, though, as he was waived in November after suffering an ankle injury.
A change of scenery didn't help his performance on the field, either. Pro Football Focus (h/t NFL.com's Kevin Patra) rated the 6'5", 330-pound Robinson as the No. 71 tackle out of 78 qualified candidates.
But a team that couldn't manage to muster a single win last season can afford to take a risk. Robinson will have to prove himself in order to make the team. If he can do so, the 25-year-old will have a chance to show he can play.
There's still time for Robinson to prove that he's not a bust, but given two teams have already given up on him, he may be running out of opportunities.
