The Pittsburgh quarterback expects to make his only preseason appearance on Saturday night when the Steelers host Indianapolis, but his bigger concern is when Bell is ready to show up to work.The Ben Roethlisberger Jerseys All-Pro running back has yet to sign his franchise tender, though he hinted on Twitter late Tuesday night that he would arrive on Sept. 1, the day after Pittsburgh plays its preseason finale against Carolina. Bell added a winking emoji just in case. And while Roethlisberger understands business is business, he admits it's a little curious Bell hasn't reached out during his training camp sabbatical. Ryan Shazier Jerseys Roethlisberger sent a couple of missives earlier in camp Bell has yet to return."I mean I'd love to hear back from him, just a text, `Hey how you doing,"' Roethlisberger said Wednesday. "But it is what it is."Meaning it will be rookie James Conner, free agent pickup Knile Davis or backup Fitzgerald Toussaint in the backfield with Roethlisberger on Saturday night. Conner made an auspicious pro debut last weekend, running for 99 yards in a win over the Falcons. Still, Conner isn't Bell. No back in the league is.While Roethlisberger isn't too concerned about Bell getting up to speed whenever he arrives, each day that goes by is a missed opportunity. Heath Miller Jerseys Roethlisberger added he hasn't tried to sneak Bell the team's updated playbook and isn't sure if anyone else has, meaning Bell will have to do a bit of cramming before the season starts for real Sept. 10 in Cleveland."That's on him and how much studying he wants to do," Roethlisberger said. "We'll do everything we can to get him up to speed and then the rest is kind of on him."Bell averaged over 150 yards of total offense in 12 games last season, helping the Le'Veon Bell Jerseys franchise to a third straight playoff berth and its second AFC North title Troy Polamalu Jerseys in three years. A groin issue hampered him in the AFC championship game against New England. Bell underwent surgery to repair the problem in the spring, but hasn't been in the locker room with his teammates since January.
