The 6'5", 315-pound Oakland Raiders offensive tackle had been expected to debut on special teams. But when starting right tackle Matt McCants injured his foot late in the second quarter, Watson filled in to replace him, The San Jose Mercury News reports.
"By all accounts, (he) held his own," according to NBC Bay Area.
Watson told reporters he wasn't nervous filling in for McCants.
"They’re men out there," he said. "It’s not machines or aliens we’re playing against, it’s just men. I’m never nervous, whoever it is. It doesn’t matter to me.”
The Raiders signed Watson in April to play for the Oakland Raiders. Since then injuries led him to a bumpy start.
