For those of us Americans wondering why you bring him on in the 60th if he was too injured to start, there are plenty of examples in pro sports all over the US where guys minutes, plays, at bats, etc. are limited because of a knock but they still play part of the game. Difference is in soccer, you don't have the luxury of playing them for 5 minutes at a stretch or using them only as a DH. They are either on the pitch or not. No problems with what Frank did plus, he gets 30+ minutes of match play/fitness without getting overly fatigue which is when reinjury typically happens.
