Saturday's game between the Tennessee Vols and Arkansas State now will be shown in HD on Comcast.
The noon game is one of three on the alternate SEC Network on Saturday.
Comcast originally was going to show the game only in standard definition.
But Alex Horwitz, vice president for public relations in the Big South Region, which includes Tennessee, wrote in an email Thursday that had changed:
"We were able to complete certain network adjustments so that Comcast customers will be able to enjoy the Tennessee-Arkansas game in HD, along with a full slate of college sports programming available on their TV and online throughout the weekend and the season."
Comcast customers ih Knoxville can find the game on 1739 & 1740 HD or761 & 762 SD
