Wigan Athletic manager Roberto Martinez has admitted he feared that Jordi Gomez had broken his leg following a challenge by Wolves' Karl Henry.
Henry was handed his marching orders in the 11th minute of the Latics' 2-0 win over Wolves at the DW Stadium.
Gomez was lucky to avoid injury, and in the second half the Spaniard struck a great free-kick to help his side to victory.
Martinez told Sky Sports HD2: "Jordi is very fortunate that he escaped damage. Straight away I thought it was a broken leg.
"The excessive force and how reckless (the challenge) was. It was a real worry.
"But after that, I didn't want the sending-off as it puts pressure on you to win and you become anxious."
Of the result, Martinez said: "It is a huge victory.
"First of all, we spoke before the game about how it would be important for whoever managed to win the three points.
"What is pleasing is that we learnt from when we played with 10 men against Sunderland.
"I am just so proud of the players. In the second half they got together and it was a pleasure to see how we played as a team."
