Oakland Raiders left offensive tackle Jared Veldheer was placed on injured reserve-designated to return with a torn left triceps that required surgery.

Offensive tackle Matt McCants was promoted from the practice squad to replace him on the roster.

It's a blow to the Raiders' offense.

Veldheer started the last 42 games at left tackle, missing just a single snap during that span.

Veldheer is a former third-round draft pick who drew high grades last season.
