Depends on what decision UT makes in terms of how many will be sold. If things go back to full attendance allowed, they will be available. If it stays limited, they might be difficult to come by, or at least expensive.
We should know later this week when UT announces how many of the full stadium seating number will be available for the Arkansas series this weekend.
Unfortunately, it's out of UT's hands. The NCAA has already issued a mandate that any team hosting a regional cap ticket sales at 50% capacity.
