The Arizona Cardinals have re-signed Chris Johnson.

With David Johnson out for three to four months, the Cardinals need more depth at running back.

Arizona cut Chris Johnson shortly before the start of the season. Johnson didn't impress during the preseason, carrying 13 times for 41 yards (3.2 yards per attempt) with a fumble.

The Pittsburgh Steelers have agreed upon a five-year, $61 million extension with Stephon Tuitt.

Tuitt is a versatile end who plays inside or out, base or nickel.

Tuitt has 11.5 sacks over 32 career starts spanning three seasons, and he gets consistent pressure.

The Buffalo Bills added $2.5 million in incentives to the contract of LeSean McCoy.

McCoy has three years remaining on his current deal.

McCoy was traded by the Philadelphia Eagles to the Bills in 2015.

Vontaze Burfict has agreed upon a three-year, $38.68 million extension with the Cincinnati Bengals.

Burfict was a Pro Bowler in 2013 after going undrafted in 2012 out of Arizona State. Burfict was expected to be a high first round pick but he had a number of red flags.

Burfict will be suspended for the first three games of the 2017 season due to a hit he made in the preseason.

Le'Veon Bell has officially signed his $12.1 million franchise tender with the Pittsburgh Steelers.

Bell averaged 157 yards from scrimmage per game last season.

Bell stayed away from the Steelers during the month of August after they failed to sign him to a long-term deal.

"I wanted to make sure I was prepared and fresh for the season," he said. "I don't want to go out there and jeopardize myself getting hurt in camp. Obviously I understand I'm on a one-year deal, so I have to go out there and prepare and play football. ... My rookie year I got hurt in camp, so I didn't even want to deal with it. I wanted to get ready for game one, the games that count and go out there and try to win a Super Bowl."

The Denver Broncos have signed Brock Osweiler on the veterans' minimum of $775,000.

Osweiler spent his four seasons with the Broncos before signing with the Houston Texans. The Texans traded him to the Cleveland Browns after one season and he was released.

The Browns, who owed Osweiler $16 million after his release, will now pay him $15.225 million.
