Mike Tomlin has admitted that Le'Veon Bell is not in "tip-top football condition" ahead of his first game for the Pittsburgh Steelers.
The rookie running back, who missed the first three games of the season with a foot sprain, will make his regular season debut for the AFC North side at Wembley Stadium later today.
The head coach told reporters: "We're excited about watching him for the first time. As for the amount of snaps, we're going to play that by ear.
"We acknowledged that he's not in tip-top football condition and the only way to get that is by playing, and he hasn't done that a lot. We're going to keep an eye on him and monitor that throughout the game."
The Steelers face the Minnesota Vikings this evening.
