Michael Vick needed a job. Pittsburgh needed a backup quarterback. One solid workout solved both problems.

The Steelers signed the four-time Pro Bowler to a one-year deal Tuesday night, hopeful there's enough game left in the 35-year-old's still dangerous legs to provide the defending AFC North champions some insurance should something happen to Ben Roethlisberger.

"There's not a throw on the field he can't make from an arm strength standpoint," Pittsburgh coach Mike Tomlin said. "He's a very experienced guy at what he does at this point in his career and the mobility is still unique even at 35."

Vick, 35, has been a free agent after playing for the New York Jets last season.

Mathis joins Broncos

Two-time Pro Bowl guard Evan Mathis agreed to a one-year deal with the Denver Broncos that could be worth up to $4 million.

The Broncos are high on rookie left guard Max Garcia, but they already have two starters — left tackle Ty Sambrailo and center Matt Paradis — who are NFL novices.

They suddenly sport one of the best guard combinations in the NFL: Mathis and Louis Vasquez were both first-team AP All-Pros in 2013.

Grossman return

Rex Grossman, who hasn't taken a snap in an NFL game since 2011, could soon join the competition to be the backup for Falcons quarterback Matt Ryan. Grossman, 35, was given a physical and a workout was planned after the team's practice.

Falcons coach Dan Quinn said he is happy with backup quarterbacks T.J. Yates and Sean Renfree. Even so, Quinn said he is always looking for ways to improve.

"It's just like at every position," Quinn said. "We're happy with the two guys we have, but when it's time to work out somebody and see where he's at or how we can improve, we're going to look at that every chance we get. I wouldn't look too much into that other than it's another opportunity for us to do that."

McCarron backup QB

The Bengals released quarterback Josh Johnson, making AJ McCarron the backup to Andy Dalton.

McCarron impressed during a 25-11 preseason loss at Tampa Bay on Monday night, going 11 of 15 for 97 yards.McCarron, a fifth-round pick from Alabama last year, missed his rookie season because of a sore passing shoulder.

Wayne finalizes deal

Reggie Wayne said he was talking to several NFL teams before deciding to sign a one-year contract with the Patriots.

"There were a lot of serious calls, from some good teams, but I felt like this was the best place," Wayne said.
