Sam Bradford: RG3 was feeling for Minnesota Vikings QB on Monday Night Football

Oct. 10 (UPI) -- Robert Griffin III was the perfect guy to play armchair quarterback Monday night while assessing Sam Bradford.

The Minnesota Vikings quarterback left the 20-17 victory against the Chicago Bears in the second quarter after aggravating his knee. Bradford was playing in his first game since the Vikings' Sept. 11 season opening win against the New Orleans Saints.

Bradford, 29, completed just 5-of-11 passes for 36 yards before exiting the game. He didn't look right from the start, but looked even worse after taking a few hits.

"Gotta get Bradford out for his own safety trust me I know the feeling," Griffin tweeted after the game.

Griffin, 27, has obviously had his share of career-defining injuries. The No. 2 overall pick in the 2012 NFL Draft made the Pro Bowl and was named Offensive Rookie of the Year during that campaign. He started 15 games this next season, seven games in 2014 and five games in 2016, before getting released by the Cleveland Browns.

A dislocated ankle shelved Griffin for six games in 2014. He lost his 2015 season after a concussion. He was out for 11 games in 2016 because of a shoulder fracture. He also suffered a concussion during the 2016 season.

Bradford was the No. 1 overall pick in the 2010 NFL Draft. He dealt with multiple ankle injuries in the 2011 season before tearing his ACL in 2013 and in 2014. Bradford missed two games in 2015 with a concussion. He also sprained his shoulder that season.
