Even though the San Francisco 49ers blew out the New York Jets 31-13 on Sunday, they ended up losing a handful of key players to injuries.

After the game, San Francisco head coach Kyle Shanahan said that the turf at Metlife Stadium in East Rutherford, New Jersey, played a significant role in the injuries.

Shanahan said that several players complained to him about the turf being sticky, saying that they were worried about injuries. Worst of all for the 49ers, they are going to be playing in the same stadium next week against the New York Giants.

The biggest injury that San Francisco suffered was to their star defensive end and last year’s Rookie of the Year, Nick Bosa. The dominant defender was carted off the field in pain and earlier indications are that he has torn his ACL and will be out for the season.

The 49ers defense suffered another huge blow, also losing defensive end Solomon Thomas. He is also believed to have torn his ACL, which leaves the defending NFC champs without two key pieces of their vaunted defensive front.

To add insult to injury, San Francisco’s starting quarterback Jimmy Garoppolo also left the game with a high-ankle sprain is expected to miss a few weeks of action.

But it doesn’t end their either. Running back Raheem Mostert suffered what the team believes is an MCL sprain. His backup Tevin Coleman also suffered a knee injury.

League officials have reported that grounds experts are going to investigate the issues at Metlife Stadium before next Sunday to see what can be improved in order to prevent further injuries.
