Pittsburgh Steelers quarterback Aaron Rodgers is feared to have suffered a 'slight break' in his left wrist, according to reports.

The NFL legend, 41, was forced off during the Steelers' game against the Cincinnati Bengals on Sunday afternoon. 

According to ESPN, there are initial concerns that Rodgers has suffered a fracture in his non-throwing wrist.

The 41-year-old will have further tests on Monday to understand the extent of the problem - and how long he will be out.

But the injury to his left wrist was bad enough for Rodgers to leave the field during the second quarter of the Steelers' 34-12 win against Cincinnati.

Footage showed Rodgers landing on his hand as he was tackled while throwing the ball on a second-and-goal.

He remained under center for one more play before heading to the sidelines. There appeared to be blood on his hand, according to ESPN.

Mason Rudolph came on to replace Rodgers and the backup quarterback led the Steelers to a win that takes them to 6-4 for the season.

It was initially reported that Rodgers was battling a hand injury before Steelers head coach Mike Tomlin confirmed it was a wrist problem.

'He was excited about the win,' Tomlin said. 'I just talked to him, but that's all we talked about. We didn't talk about his injury. We talked about the significance of the win.'

When asked whether Rodgers could have returned in the second half, Tomlin added: 'I don't have the answer to that to be honest with you... I'll have more information next time we talk.'

Rodgers has enjoyed a fine start to his career in Pittsburgh. The 41-year-old has led the Steelers to the top of the AFC North in what he is 'pretty sure' will be his final season in the NFL.

He moved to Pittsburgh after two miserable years with the New York Jets, which began with an Achilles tear just four snaps into his debut.
