Injuries to both Arjen Robben and Jerome Boateng forced Bayern Munich manager Jupp Heynckes to reshuffle his lineup early in Wednesday's Champions League semi-final first leg versus Real Madrid.
Thiago Alcantara and Niklas Sule replaced their teammates in the seventh and 33rd minutes, respectively.
Robben appeared to tweak his thigh after kick-of, while Boateng was seemingly bothered by a hamstring issue.
The pair of untimely changes left Heynckes with just one substitution remaining.
Madrid scored a crucial away goal to level the match at 1-1 shortly after Boateng's departure.
Robben has struggled with a combination of muscular injuries and nerve problems this season, alternating time on and off the pitch. Boateng, meanwhile, had a troublesome 2017 that featured a months-long spell on the sidelines.
