JPP has burns on palm, 3 fingers. 1 finger could have nerve damage. Didn't lose any fingers, team thinks he'll be OK, per @DanGrazianoESPN.— Adam Schefter (@AdamSchefter) July 6, 2015
Pierre-Paul's injuries are not considered to be career-threatening.
Pierre-Paul has skipped all of the Giants' off-season activities including a mandatory mini camp in June, because he is still looking for a long-term contract.
