The midfielder was a key member of the Sheffield Wednesday side that reached the play-offs twice in a row.
Lee hasn't appeared for Wednesday's first-team since December 2017 owing to injury.
But the 30-year-old has now played more than 100 minutes of under-23 team football in the space of eight days.
And with (at least) four first-team fixtures still to be played, there's a chance Lee could make his comeback before the season's out.
If not, well Monday's run-out might be the last we see of Lee in Sheffield Wednesday colours, as his contract nears expiry.
And while some of an Owls persuasion are keen for him to stick around, not everyone agrees.
This is what they're saying on Twitter...
If Bruce is satisfied Kieran Lee is fully recovered, I'd love him to get a new contract and play regularly next season. Arguably our best midfielder in my opinion. It's a big "if" on such a long term injury though.... #swfc— Steve Turner (@Majortarantino) 15 April 2019
Agree with all that George Kieran lee has to worth a gamble if we can afford it— Robert Dawtry (@todwickrobswfc) April 16, 2019
Yes George if he proves his fitness— Malcolm Fox ⚪️ (@malcolm_fox2) 15 April 2019
Yes. But let him prove that he can be first choice. Same with Hooper.— Josh (@Jaybe07) 16 April 2019
Get rid of Abdi, Nuhiu, Jones, Van Aken, Pudil, Winnall.
And then bring a couple of younger players in. #SWFC
You can’t buy class like Lee and Hooper for under 5 million.
Small weekly wage with an appearance heavy bonus on his contract 1 year deal, I would think he’d snap our hand off at that— Brett Oldfield (@brett_oldfield) 15 April 2019
Needs a nuance option here. I would but deffo play time based, or on very reduced wages, with a promotion bonus/appearance bonus— • adam • (@_ae19_) 15 April 2019
Pay as you play contract or nothing for me— Craig Barton (@barton6435) 16 April 2019
I voted a very sad no. I'd like the owls to bring in a younger version of Keiran Lee. To much of a risk, will he ever be the same? Will his hip collapse? He's bound to have lost some zip & pace. Love the lad, but imo we've seen & had the best from him.— keiron wilcock (@keiron1972) 15 April 2019
Unfortunately no for both him and Hooper imo. We need fresh input rather than relying on the same 4/5 to be fit and on form. Plus the Wednesday curse will no doubt stike them down again— Robbie Jamieson (@robbiej2906) 15 April 2019
Loved him at club but time to go ! We haven’t got the money to be taking gambles and that goes for hoops too— Tony Hinds (@tonyblueowl) 16 April 2019
Nope. Same as hooper. Both to move on. We need energy + mobility and neither will help with that. KL very unlikely to get round a pitch like he did. Say thanks and good luck.— Barx (@Barx_SB) 15 April 2019
One of the league's most underrated players but No, too injury prone. Time to move on from players like that— Gary Atkin (@Gary_A89) 15 April 2019
Lee was a regular in the Sheffield Wednesday sides that reached the play-offs in 2016 and 2017, and it's fair to say his presence has been missed throughout the past 16 months.
The former Manchester United player has scored or made 32 goals in 185 games for the Owls.
Should Wednesday hand Lee a new deal?
