The Brazilian striker was taken off in stoppage-time at the end of Brentford’s 3-1 win over Burnley and Keith Andrews said he would undergo a late fitness test.
Thiago has been central to Brentford’s success this season, with his brace against struggling Burnley taking him to 11 goals in 13 Premier League games.
The 24-year-old was withdrawn as a precaution against Burnley, with Andrews admitting he was dealing with a few knocks.
"We've got a couple of knocks and bruises," Andrews told reporters. "But you get that from a game like the one we had at the weekend.

"We've got a couple of bits and bobs that we'll have to decide on but, in the main, we're in a good place."
Brentford will make a late call on whether to involve Thiago against Arsenal, while Josh Dasilva, Fabio Carvalho and Antoni Milambo remain long-term absentees.
Reiss Nelson, who is on loan from Arsenal, is unavailable to play against his parent club.
Midfielder Yehor Yarmoliuk is expected to come back in to the team after being benched against Burnley.

Thiago, who became the fastest Brentford player to score 10 Premier League goals, endured an injury-hit debut campaign in west London.
But he is fit again this season and has been a revelation for Andrews, who admitted the former Club Brugge frontman is a joy to work with.
"He is a dream to work with. As a person, his hunger and appetite to get better is impressive,” Andrews said.
"He is having a fantastic season, it doesn’t take a genius to see that. The numbers will tell you that, the performances he produces consistently well, how well he has integrated into the way they are playing and with individuals.
“He is making a real impact on how we are playing and proving to be a big player for us."
