Kansas City Chiefs offensive tackle Eric Fisher is set to sit out Super Bowl LV against the Tampa Bay Buccaneers after suffering a torn Achilles tendon.

Chiefs head coach Andy Reid confirmed the injury a day after the reigning NFL champions topped the Buffalo Bills 38-24 in the AFC Championship Game on Sunday.

Fisher – a two-time Pro Bowler after being selected first in the 2013 NFL Draft – won the Super Bowl with the Chiefs last season as Kansas City claimed their first championship in 50 years.

But the 30-year-old will not feature in back-to-back Super Bowls after being helped off the field against the Bills at Arrowhead Stadium.

Fisher played in all 15 regular-season games this campaign and both playoff matchups for the Chiefs.

Kansas City's offensive-line depth has been tested this season due to injuries and players opting out before the start of training campaign.

Ahead of the February 7 Super Bowl at Raymond Jones Stadium – the home of Tom Brady's Buccaneers – Reid told reporters on Monday: "They're talented guys.

"In some cases we've had some young guys step in and ... we've had some older guys step in. That combination has been able to get us through some games here. Most of all, I think the quarterback trusts them, as do the running backs.''

Should the Chiefs retain their crown, star quarterback Patrick Mahomes would be the youngest starting QB (25) to win multiple Super Bowls, surpassing Brady (26).

Mahomes joined Kurt Warner, Brady and Russell Wilson as the only quarterbacks to reach the Super Bowl twice in their first four NFL seasons, per NFL Research. The reigning Super Bowl MVP will have to beat Brady to join him as the only QBs to win it twice in that span.
