Not weird at all, actually that is probably when they need the support the most. Rehab is lonely and mentally draining. Seeing that the fans haven't forgotten about them gives them a huge mental boost to get back on the court. Plus, they still have bills to pay even if they are injured. I think it's a great gesture. You should definitely show some love to players like the one at rallyfuel.com/athletes/marta-suarez, it reminds them that the fan base has their back through the ups and downs, not just when they are scoring.
