The UFC’s upcoming visit to Berlin has hit a bump in the road.

According to a report from Combate, Brazilian Thiago Tavares has suffered a thigh injury and is out of his main card bout against Finnish feathweight Tom Niinimäki on May 31.

The 29-year-old Tavares was expected to make his 145-pound debut in the opening bout of the night’s main card. He was last in action in November at UFC Fight Night 32, where he submitted Justin Salas in the first round. Tavares has compiled a record of 8-5-1 inside the Octagon while competing at lightweight. This is the second time that he’s been forced out of a bout in 2014 due to injury. Tavares was expected to face promotional newcomer Zubair Tuhugov at UFC Fight Night 36 in Februar,y but suffered a rib injury.

For Niinimäki, his appearance on the Berlin card marks his second fight with the promotion. The 31-year-old is riding a 12-fight winning streak that dates back to 2006. The well-round veteran edged Rani Yahya in his promotional debut at the TUF 18 Finale in November. “Stoneface” hold seven wins via knockout, eight by submission and six on the scorecards.

The UFC has yet to confirm Tavares’ withdrawal from the card or name a replacement opponent for Niinimäki.

It will be headlined by a five-round middleweight bout between Mark Munoz and former Strikeforce title holder Gegard Mousasi.
