Polk, who signed as a free agent from the Eagles in the offseason, had been pegged as a third-down back, but could see an expanded role due to Arian Foster's groin injury, the Houston Chronicle reports. "I view myself as doing everything, running, passing game, blocking — whatever they want me to do," Polk said. "I just make sure I can do everything, so when my number is called, I won't let them down."

Analysis:

Polk scored seven touchdowns over his last two seasons as a reserve in Philadelphia. We expect Polk to get a long look when the Texans kick off the preseason Saturday against the 49ers.
