The ex-England goalkeeper, on just his fourth Premier League start for the Eagles, made a fine save from Leandro Trossard when the Seagulls midfielder was let through in a one-on-one head before registering his very first penalty in the elite of Pascal Gross.
Conor Gallagher appeared to have snatched a shock victory from a dominating Brighton side before Joachim Andersen’s final own goal, which Butland could do nothing to prevent.
Butland’s performance may have deserved more than a point, but the Palace boss is full of praise.
“Jack is a true professional,” Vieira said.
“He is a positive professional. He was frustrated not to play but he never complained or showed it, he kept working hard and when the attackers want to finish he is the first to lift hand. He’s a very good character in the locker room.
“I’m really happy he got this game and this performance because all the work he put in paid off today.”
