Ipswich have signed striker Chris Wood on loan from Leicester until the end of the season.
Watford have announced the signing of Italy international Marco Motta, subject to international clearance.
Terry Butcher has told Jonny Hayes to remain a central figure at Inverness and reject overtures to go elsewhere.
The 24-year-old Irish winger is out of contract this summer and Butcher is planning talks after Saturday's final match of the Clydesdale Bank Premier League season against Hibernian.
With Aberdeen and other clubs interested, Butcher plans to offer Hayes a two-year deal, believing one more season in the Highlands could be enough for the winger to then go to a future destination of his choosing.
The former England captain urged Hayes to look the example of Adam Rooney, who signed for Birmingham last summer but has been a bit-part player for the Blues this season.
Butcher said: "Do you want to be just a squad player? Jonny's one that needs to play all the time and he's a character and a very good player that should play all the time.
"Adam's moved, what's the rush to move? I want to sign Jonny on a two-year deal. Have a good year here and then you might have the pick of your clubs after that year.
"His choice of clubs now might be limited, but if he has a good season with us in the SPL and he does really well, then he might be able to go to a club that he wants to go to.
"When Jonny came here his career was going nowhere. When we first saw him I thought 'Wow, we've got something special here' and we have, even more so now.
"Loyalty is a great thing in football. It's very rare. But when you look at what the club's done for Jonny and what he's given to the club, it's been a good marriage."
Unless he agrees a new deal, Hayes could feature for Inverness for the final time this weekend, when Butcher will demand a fifth home win of the season.
Butcher said: "I want our players to go out there and play for these three points as if it's the most vital three points of the season.
"Hibs have beaten us twice, we think unfairly. We should've got at least two draws from those matches, if not six points.
"But it's not about making amends on Saturday, it's about finishing it off well and making sure we beat Hibs this season, which we haven't done."
Hibs play in the first all-Edinburgh Scottish Cup final since 1896 the following week, seeking to win the trophy for the first time in 110 years, and Butcher believes counterpart Pat Fenlon will be fearful of the trip to Inverness.
"He realises coming up here is one of the worst places he could possibly visit the game before the cup final because we'll be bang at it," Butcher said.
"I know what I would do. I'd rest a few people to make sure you could be immortalised by beating Hearts in the final and you don't want anything coming in your way."
