Here's my injury log & summary details as of the end of last season
21 injuries this season, one every 1.3 days on average, two days in a row I had 2 in a match in the league, away games at abandoned teams with rubbish pitches which blew out the average. My star striker Alawa was injured 3 times, but 41 goals in 29 matches is worth a few med packs!

Early last season lots of people were reporting an increase in injuries in friendlies, including me, but that levelled out over the season. Note for Cat, I play a 22-man squad, same as you, and I try to only give players 1 match a day, plus 1 of each type of training (with occasional power training on top), and I never play/train anyone who's below 80% rested. So you could use my injury probabilities as a guide - basically a 1 in 5 chance of an injury in any match*, and a 1 in 15-20 chance** in any training.

Early days, but it looks a bit like injuries fall into 3 or 4 classes: Common (ankle strain & grade 1 hammy), moderate (hammy grade 2/3, ACL, Knee Cartilage), lower moderate (thigh/groin/heavy ankle strain) and rare (the rest)
* if you play 2 matches a day that's a 40% chance of at least 1 injury across the squad. If you play 5 or more (Sid, I'm looking at you
) you can EXPECT at least 1 injury a day - though if you're using rest packs pre-match that may drop a little
** So 1 of each type of training a day = a 1 in 5 or 6 chance of an injury.
Combining the above, I average 0.6 injuries per day. People who work their squads harder should expect more than that.
