LATROBE, Pa. -- No holdout for left tackle Alejandro Villanueva, who is signing a four-year extension with the Pittsburgh Steelers, a source told ESPN. Villanueva is arriving to camp now to sign his deal. Villaneuva, 28, wasn't under contract because he hadn't signed his exclusive rights tender of $615,000. The two-year starter made significant strides in the second half of 2016 and is a key component to one of the league's best offensive lines.
