Actually, the rules state differently. 3-5-10a being the relevant rule.
A time out occurs when
1) injured player is discovered
a) While the ball is dead AND for whom the RFP is delayed or
b) For whom the clock is stopped.

So, if the clock was stopped to enforce a penalty, the clock stoppage requirements of the rule are not met unless it takes more time to "fix" the injury than it does to enforce the penalty and mark the ball ready. Which for most injuries is going to be the case as the coaches/trainers do their bit for the guy hurt on the ground. But for a quick cut that needs to be covered, could happen.
