LATROBE, Pa. -- Steelers rookie quarterback Will Howard sustained an injury to his throwing hand during Tuesday's practice, coach Mike Tomlin said.
Howard, a sixth-round pick, is believed to have injured his hand on a center-quarterback exchange and will be further evaluated.
"I think it was a CQ exchange," Tomlin said. "But I didn't have direct eyes on it, so I'm speculating."
Tomlin added that TE Jonnu Smith left practice early with knee soreness but it appears to be "less significant," and OLB Alex Highsmith missed practice with a groin injury sustained Sunday that will keep him out "a couple days at least.
