**It may be hump day, but the news cycle never stops, with plenty of Guinness PRO14 goings on to report.** We had movers and shakers, injury woes and changes at the top – it was a busy Tuesday indeed. Let’s start in Wales, with the news of a new man at the helm at the Liberty Stadium. Ospreys announced yesterday that Harlequins assistant coach Toby Booth will take charge of the region from the start of next season, and according to performance director Mike Ruddock, [it was a collective decision](http://www.dai-sport.com/ospreys-players-gave-toby-booth-thumbs-says-mike-ruddock/) that saw Booth get the nod. Up the road in Llanelli came the exciting news that Liam Williams would be returning to Scarlets earlier than expected. It was announced back in December that the Wales international would be heading back to Parc y Scarlets at the end of the season, but yesterday his Saracens departure was brought forward, to [take place with immediate effect.](https://www.bbc.co.uk/sport/rugby-union/51628224) There was further player movement in Belfast, as Alby Mathewson was picked up by Ulster on a [one-year deal](https://www.irishmirror.ie/sport/rugby-union/alby-mathewson-set-join-ulster-21575536) to begin in the summer.

And Cardiff Blues could be forced to deal with an almost identical issue, with their own young flyer Josh Adams out for the duration of the Six Nations with an [ankle injury.](https://www.bbc.co.uk/sport/rugby-union/51630969) We finish on a more positive note, however – for Glasgow Warriors fans at least – as Grant Stewart put pen to paper on a two-year contract extension that will [keep him at Scotstoun until the summer of 2022.](https://www.scotsman.com/sport/rugby-union/grant-stewart-signs-for-two-more-years-t-glasgow-warriors-1-5095249)
