Pittsburgh Steelers quarterback Ben Roethlisberger left practice on Tuesday after throwing a practice and falling to the ground, according to Ed Bouchette of the Pittsburgh Post-Gazette.

Few details are available otherwise, and we don't know yet what injury Roethlisberger could possibly have. For now, the Steelers can only hope that their franchise player was indeed only precautionary, and he didn't get seriously hurt.

Roethlisberger has been injured multiple times throughout his career, missing a game in 2016 after suffering a knee injury. He also missed four games in 2015, following an MCL and left foot injury.

Now 36 years of age, Roethlisberger hasn't showed any signs of slowing down, and the Steelers simply need Big Ben to stay healthy. Though backup Landry Jones has shown a few flashes, Roethlisberger is by far a top-five quarterback in the NFL and is impossible to replace.

Pittsburgh followed up a 2016 AFC Championship Game appearance with a 13-win season in 2017, though they were eliminated by the Jacksonville Jaguars in the Divisional Round. The goal now is for them to bring home a seventh Lombardi Trophy to the Steel City, and that's only possible if Big Ben is healthy.

Roethlisberger is a two-time Super Bowl champion, six-time Pro Bowler and is a lock for the Hall of Fame at this point of his career. The Steelers' record without Roethlisberger since 2012 is not pretty, so it's absolutely imperative that this injury isn't serious, and that he'll be ready to go for Week 1.

Big Ben tossed 4,251 yards, 28 touchdowns and 14 interceptions in 2017, and the Steelers were by far the best team in the AFC. But a late-season meltdown and porous performance against Jacksonville ended a promising season.

A healthy Roethlisberger might make the Steelers the top team in all of football. But for now, we sit back and can only hope he's not seriously injured.
