It was typical of the man that Gus was everywhere right up to that test in injury time in what was his first action since breaking his wrist against Sporting Lisbon on August 11.
Having scored our equaliser and set up Stephane Dalmat's winner in the 2-1 victory, Gus threw himself at full length across the floor to block Richard Noble's goalbound effort in the last seconds.
Asked if his wrist came through unscathed, Gus beamed: "Just look at the end, they had a chance to score so I had to throw myself at the ball.
"I had a laugh with the lads afterwards and said 'I risked my wrist for you' but that's football.
"I said before that I would have to risk it a little to play again so quickly but I didn't feel anything. Perhaps when I really land on it we'll see but so far it's fine."

Ever-enthusiastic Gus was buzzing after helping inspire Colin's men to their first win in the FA Premier Reserve League this season.
He linked up superbly with Stephane Dalmat to bag the equaliser and return the compliment for Dalmat to score the winner.
Dalmat's quick feet and bursts of pace created both goals and, alongside John Jackson in midfield, made sure we got on top and stayed there.
Gus reflected: "Sometimes when you play like we did in the first half - passing the ball, chances and then West Ham get a goal like that, a cracking goal, it looks like the second half could be worse.
"But we talked in the dressing room, Colin Calderwood was great at half-time, told us to keep passing, keep playing and I thought we came back well.
"I thought the lads were fantastic and there were times we were passing the ball in the way I love to play.
"West Ham were great, they had three or four players who could easily play for their first team at any time, so with that in mind it was a very good performance."
Gus Poyet loved every second of his goalscoring return for the reserves against West Ham last night - including a full test of his recovering wrist in injury time.
