Wigan Athletic boss Roberto Martinez has revealed that he hopes to have Ben Watson back in contention in February.
The midfielder suffered a fractured shin during the Latics' 3-0 defeat to Liverpool last weekend.
It was feared that Watson would be sidelined for a prolonged period of time, but Wigan announced on Monday that they expected him back 'in the New Year'.
Martinez has now offered a further update, with it possible that he could welcome the 27-year-old back into his plans inside three months.
"After the plaster comes off in the New Year, you're then looking at a block of about three or four weeks to get the full fitness back - which is around the beginning of February," he said in the Wigan Evening Post.
Meanwhile, Martinez has also been looking ahead to Wigan's Premier League clash with Reading on Saturday, a game he considers to be crucial to the Latics' top-flight cause.
"It's a massive game, because all of your home games in the Premier League come into that category," he said.
"Every game at the DW has been very exciting, although we haven't managed to pick up as many points as we have probably deserved."
He added: "Reading will present a completely different challenge to the ones we have faced.
"They will be coming here on a massive high after beating Everton, and will be full of confidence because of that.
"We are coming in after two defeats, but we are at home and we have to be prepared to perform as well as we can. It's a game where we can't afford to be below our best."
Northern Ireland international defender Hodson, 21, has been a member of the Hornets' first team for three years, while Italian Under-19 international striker Trotta has previously been on the books of Manchester City and Napoli and scored eight goals in eight games during a loan spell at Wycombe last season.
Both players are available for Brentford's clash at home to promotion-chasing Sheffield United in League One on Saturday.
Mark Warburton, Brentford FC Sporting Director, told the club's official website: "Marcello is a player we have admired for a long period.
"He had a very successful loan period at Wycombe Wanderers and has been very near to joining several Championship clubs over the last few weeks. We are delighted to welcome him to Griffin Park and look forward to what we hope will be a very beneficial loan spell for all parties.
"Lee has made almost 100 appearances for Watford in the Championship and has established himself as a regular full International with Northern Ireland."
