Pittsburgh Steelers star quarterback Ben Roethlisberger will have surgery on his right elbow and miss the remainder of the season, coach Mike Tomlin announced Monday.

In a statement released by the team, Tomlin announced that Roethlisberger will undergo the surgery at some point this week after undergoing an MRI on Sunday night.

The Steelers, who will place Roethlisberger on injured reserve, have not yet provided details about the injury.

Roethlisberger, 37, suffered the injury late in the second quarter of Sunday’s 28-26 loss to the Seattle Seahawks, grabbing his elbow after attempting a pass on the team’s final drive of the half. He briefly went into the locker room but was on the sideline for the last two minutes of the first half and for all the second half.

In Roethlisberger’s absence, second-year quarterback Mason Rudolph nearly led the Steelers to a fourth-quarter comeback in his first career appearance, completing 12 of 19 attempts for 112 yards, two touchdowns and an interception.
