If our guys couldn't pass sample B of a PED test it would seem that all 3 would get the same half-season suspension that was laid on Will Grier. Regardless of whether or not it's a playoff or bowl game. To do anything less would be a major flaw in the NCAA's judgment again.
The fact it's being reported that it's the Orange Bowl could be evidence it's not a drug suspension.
There is a difference in a University test and an NCAA test. If the University test positive for non-PED like marijuana, the NCAA isn't notified and the punishment is handled by the policies set forward by the University. I believe the only time the NCAA would be notified of a University test of positive would be for PEDs. The Clemson kids where hit for a PED violation on a University test, and if the sample B confirms they'll lose 50% of the next year too.
I'm not sure what Alabama's currently policy is, but it used to be 1st - none, 2nd 15%, 3rd 1 year, 4th dismissal. So if this was a 1st offense, the player would be able to play right away; however, being a bowl game where the NCAA is testing they may be suspended and left home to avoid a possible failed NCAA test. If it's a 2nd offense then they'd miss two games.
Again, we don't know what they did to get a 1 game suspension so it's just speculation. I'm just basing my GUESS on the high likely hood of marijuana use among many of the players and students and the timing makes it a very likely possibility.
