American forward Haji Wright's first Bundesliga goal was not enough to save Schalke from a 2-1 loss that gave Bayer Leverkusen coach Heiko Herrlich a lifeline on Wednesday.
Herrlich was under pressure after the side's defeat at Eintracht Frankfurt on Sunday.
Instead it is the home side's coach, Domenico Tedesco, who must fret over his future after his team was whistled off by their own fans at full time. Schalke dropped to 16th, one point above the relegation zone with one game to play before the halfway stage of the season.
Leverkusen was reportedly already in touch with former Borussia Dortmund coach Peter Bosz and Salzburg coach Marco Rose as potential successors for Herrlich after a lacklustre season so far.
Leverkusen sporting director Rudi Voeller was noncommittal when asked about his coach's future before kickoff in Gelsenkirchen.
But Herrlich, who took over before last season, was given some respite after first-half goals from Aleksandar Dragovic and Lucas Alario.
The 20-year-old Wright also scored before the break, set up by compatriot Weston McKennie, but Leverkusen held out for their sixth win in 16 games.
